Looker Studio (formerly Google Data Studio) is a free data visualisation and business intelligence tool from Google that allows you to create interactive, shareable dashboards and reports by connecting to data sources including GA4, Google Ads, Google Search Console, BigQuery, spreadsheets, and hundreds of third-party sources via connectors. It transforms raw analytics data into clear visual reports — charts, tables, scorecards, and maps — that make marketing performance immediately understandable to stakeholders who are not comfortable navigating GA4 directly.
Looker Studio is particularly valuable for agencies and marketing teams who need to report performance to clients or leadership in an accessible format. A well-designed Looker Studio dashboard can show a month's worth of marketing performance at a glance — traffic by channel, conversion trends, keyword rankings, and ad spend efficiency — in a single view that automatically updates with live data.
What Looker Studio can connect to
- Google Analytics 4 — website traffic, conversions, user behaviour, and audience data
- Google Ads — campaign performance, spend, CPC, conversion data, and quality scores
- Google Search Console — organic search impressions, clicks, CTR, and keyword rankings
- YouTube Analytics — video views, watch time, subscriber growth, and revenue
- Spreadsheets — Google Sheets and Excel files for manual data that does not have an API
- BigQuery — large-scale data warehousing for enterprise analytics
- Third-party connectors — Supermetrics, windsor.ai, and similar tools enable connections to Meta Ads, LinkedIn Ads, TikTok Ads, Klaviyo, and many more
Building your first Looker Studio marketing dashboard
A useful basic marketing dashboard for a UK business should include: total sessions this month vs. last month and vs. same period last year; sessions by channel (organic, paid, social, email, direct); top-performing pages by sessions and engagement; conversion rate and total conversions by channel; and cost per conversion if Google Ads data is connected. This can be built in 2–4 hours using Looker Studio's native GA4 connector. Once built, the dashboard updates automatically as new data comes in, and can be shared via a link or embedded in a website.
Looker Studio (the standard version) is completely free. Google also offers Looker Studio Pro — a paid enterprise version with team workspaces, stricter access controls, and enhanced support — but the free version provides all the functionality the vast majority of UK businesses need. The cost of third-party data connectors (like Supermetrics for Meta Ads or LinkedIn Ads data) is separate — these typically cost £50–£200/month depending on data sources required. For businesses only using Google's own products (GA4, Google Ads, Search Console), Looker Studio is entirely free end-to-end.
GA4 is the data collection and analysis platform — it gathers, processes, and stores your website analytics data and provides built-in reporting. Looker Studio is a visualisation and presentation layer — it reads data from GA4 (and other sources) and presents it in customised visual formats. You need GA4 to collect the data; Looker Studio helps you present and share that data more clearly. Most UK businesses use both: GA4 for detailed analysis and exploration, Looker Studio for regular performance reporting to stakeholders.
